clk: si521xx: Use REGCACHE_FLAT instead of NONE
[ Upstream commit f03a562450eef35b785a814005ed164a89dfb2db ]
In order to reload registers into the clock generator on resume using
regcache_sync(), it is necessary to select one of the regcache types
which are not NONE. Since this device has some 7 registers, use the
simplest one, FLAT. The regcache code complains about REGCACHE_NONE
being selected and generates a WARNING, this fixes that warning.
